This invention relates to spinning frame cleaners. Duringthe operation of spinning frames, fly and dust are deposited on the creel boards in such quantities that, unless thecreel boards are frequently cleaned, parts of the fly become attached to the rovings be ing drawn from the creel causing breakages in the drawing rolls or imperfections in the spun yarn. Notwithstandingthe importance of creel board cleaning, such cleaning has heretofore invariably been done manually,

and has been subject to'the unc'ertainties of any manual operation. Y Thus, inattentive ness or neglect by operatives or the use of an insuflicient number of operatives have frequently resulted in allowing fly to collect on the creelboards with consequent imperfections in the yarn.

The present invention provides automatic means for efi'ecting'the important operation of creel board cleaning, thereby preventing imperfections in the yarn and reducing the amount of labor required in spinning mills.

In accordance with the invention, a wiper of'each of the creel boards on which fly is likely to collect, and is moved about substantially the whole upper surfaceof this creel board by means actuated from a power-driv- 3 en part of the frame. .Thus, whenever the operation. 1 V 1 In order that my invention may clearlyv be understood, I will describe in detail the specific embodiment of'the inventionwhich is shown in the accompanying drawings in which? i Fig. 1 is a side elevation of part of the creel of a spinning frame'showing thecleaners;

' The'drawings show. a spinning frame creel consisting of superposed creel boards 1, 2 supported in vertical end frames 3. They indicatea part 4 of one of the verticalcontrol rods of the spinning frame which customari- 1y extend upward through the middle of the creel..- The drawings also indicate a roll stand 5 and the lower drawing rolls including a power-driven fluted draft roll 6.

Roving bobbins 7 are suspended from the yupper creel board (not shown) and the inof the bobbins 7. i v ."Wi'pers9 rest on'the upper surfaces of the lower and intermediate creel boards 1, 2, and are moved aboutthese surfaces under the lower ends of the bobbins 7 by mechanismdriven from a power-driven part of the spinning frame. In the form shown, the power is takenfrom abelt pulley 10 which is fixed by means of a screw 11 on one end of the powerbelt 14, this pulley lOdrives a pulley 15 fixed ona'shortspindle 17 journalled'in brackets 18 secured to the outer side of one of the end frames 3 of the creel. vAnother pulley 19 21 passing through holes 22 in the end frame 3 with a-pulley 24 fixed" on a vertical shaft 25 y j ournalled Y in the lower and intermediate creel boardsl, 2 and extending a short distance above theintermediate creel board 2.

Pulleys26 are fixed on this vertical shaft a short distance above the. upper surfaces of thelower and intermediate creel boards 1, 2, and'serve to drive endless belts 27 which lie close to the upper'surfaces of the lower and intermediate creel boards 1, 2 and pass around idler pulleys'28 secured to the creel boards. The wipers 9.are secured to these belts 27 and by them are carried about the upper surfaces of the creel boards.

As clearly shown in Fig. 2, the fixed pulleys 26 and idler pulleys 28 are so positioned that the endless pulley belts 27 have their reaches close to, and at opposite sides of, the middle lines of the creel boards 1, 2, so that the control rods '4 of the spinning frame, one of which is shown inFigs. 1 and 2, pass'between the two reaches of each belt 27. One or more wipers 9 are secured to each endless belt 27 so as to extend outwardly therefrom. In-the form shown in the drawings, two wipers are used on each belt, but this'is not essentiaL. The wipers 9 are long enough to extend 'outwardly from the reaches-of the'belt 27 to the outer edges of the creel board, and outwardly fromthe pulleys 26, 28 substantially to the ends of the creel board, so that, as they travel around on thebelt 27, they wipe substantially the entire surface of the creel board, except the middle. portion of it which. is located inside the belt, that is, between the two reaches of the belt. To provide for wiping this portion, the wipers 9 are provided'with wiping extensions 81 at their inner ends. These extensions 31 are lower'than the main. body of the wiper 9 so that they may pass under the belt 27. They are slightly longer than the radius of the pulleys 26, 28 or half the distance between the two reaches of the belt 27 'In order to enable the extensions- 31 to pass the shaft 25 on which the driving 31are made flexible and resilient so that they yield and bend when striking one of these obstructions and re-assume their normal position after passing it. When two or more wipers are used on a single belt, their wiping extensions 31. yield to pass each other, as shown in Fig. 7.

It will be understood that the arrangement which has been .described results in continual wiping of all portions of the upper surfaces of the creel board.

' While the invention in its broader aspects is independent of the specific form of the wipers or the means by which they are attached to the belts 27 a feature of the invention consists in a wiper 9 of a particular con- .struction which I have found to possessspebest illustrated in Figs. 4, 5,6 and The wiper illustrated. has a rigid body 34 in whose lower surface are longitudinal grooves in which are secured strips35-of'felt which do the actual wiping. These strips 35 project some distance fromthe lower surface of the body 34, and two of them extend beyond the inner end of the body to' provide the low wiping extensions 21. In the middle of the inner end of the body is an arcuate recess having substantially the same radius as the pulleys 26, 28. The spaced portions of the inner end of the body at the opposite cial'advantages. This wiper constructionis sides of this recess are the belt-engaging portions of the body and are most desirably provided with felt pads 36. The wiper 9 is attached to the belt 27 by means of a tension spring 37 having one of its ends secured to the body 34 and the other to the belt 27 and lying in a longitudinal groove '38 extending into the body 34 from the middle of the arcuate recess. I

The advantages of the construction described are that the wiper always extends straight out from the belt and passes around the pulleys without materially changing the tension ofthe belt.. lVhen the wiper 9 is on a straight reach of the belt 27, the spring 37 draws the belt 27 into the arcuate recess, holding it in firm contact with the spaced beltengaging portions 36 of the body'34, sothat the wiper projects outwardly at right angles to the belt.. When the wiper 9 is on a part of the belt 27 which is passing around one of the pulleys 26, 28, this arcuate portion of the belt engages the arcuate recess in the body 34 of the wiper, so that the wiper projects radially from this portion of the belt.
